<p>The Summit 10000 power bank combines the lightweight and steady carbon fiber frame with an innovative low temperature resistance at -40 degrees C/F. Normal power banks drop efficiency significantly in cold climates. Summit 10000 can still charge a modern smartphone two times over on top of Mount Everest. The Summit 10000 comes with dual ports, a QC PD USB-C port that can fast charge the power bank or quick charge other devices at 18W and 20W respectively, as well as a USB-A QC output port to charge others.The Nitecore Summit 10000 is built with a unibody carbon fiber shell making it steady and extremely lightweight at only 6.07 ounces. The seamless design is not only 1.5 meters impact resistant, but also IPx5-rated water resistant ready for outdoor use. Summit 10000s intelligent heating function automatically kicks in when the temperature is below the freezing point. The heating function consumes ultra low power while keeping the power bank at an appropriate temperature to avoid loss of power or efficiency in cold climates. In addition, the Summit 10000 comes with an insulated carrying bag as well as a braided USB-C to C cable for reliable power transfer. It takes power to make it to the top, so why not the Nitecore Summit 10000!</p><ul><li>?Low Temperature</li><li>?10000mAh LOW TEMP POWER BANK - The Summit 10000 power bank is low temperature resistance up to -40?
